Regularities of Ammonium Nitrogen Distribution in Calcisols

Resumo

Ammonium nitrogen (N-NH₄) concentration in the calcisols of the Nikitsky Botanical Garden shows considerable spatiotemporal variation. This study has shown an extremely close correlation and corresponding linear relationships between nitrogen stores in the different soil layers and the average monthly temperature as well as between the logarithms of N-NH₄ concentration values and depth.
